'A CI is desired for the true average stray-load loss ,u (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. Assume that stray-load loss is normally distributed with = 3.0. a. Compute a 95% CI for p. when a = 25 and E = 58.3. b. Compute a 95% CI for ,u, when n = 100 and 3' = 58.3. c. Compute a 99% CI for p. when n = 100 and E = 58.3. (I. Compute an 82% CI for I1 when n = 100 and Tr = 58.3. e. How large must it be it' the width of the 99% interval for ,u is to be 1.0
